I'm not doing any active work on it at the moment, but my favorite approach has been Mark Jones' active production networks, which are one of those schemes that lies in the twilight between symbolic and connectionist. Like Copycat, it is based on a semantic net with spreading activation and variable connection strengths. The network looks like the tree of a grammar, with lots of extra links, and the text is fed in by sequentialy "lighting up" the terminal nodes that correspond to words. After each one, the network reconfigures itself to interpret the next word/phrase appropriately.
There is no formal distinction between nodes holding syntactic and semantic information. Indeed, if you "light up" nodes corresponding to a semantic situation, the network can be jogged to produce sentences describing it.
